Not working??

I installed WPbruiser for my jetpack contact form (with a name, email, message field).
In the WPBruiser settings I selected ‘Jetpack contact form’ under the contact forms tab.

So I decided to do some testing… I submitted forms with texts like:
buy viagra very cheap, call 555039530502 and that kind of stuff.

The messages were submitted, but very slowly.
All messages could be found in the admin feedback section, and none were marked as spam.

So either I’m doing something wrong here, or this plugin simply ain’t working. Any help would be appreciated.
